Anybody done this

Yes, in principle. I think there was a bug last time I tried, but I
have done it. The SCM scheme system, for instance, also does this
(with caveats) via unexec and might be a better example. (This might
well not be the best technique to dump and restore an Erlang system if
that was really wanted.)

Sorry. A web search found no relevant mentions in an Erlang context,
which surprised me; hence the question. Can one read about it
somewhere?
